PC just randomly won't POST until 6-pin power on GPU removed and put back again

[Michael]

A friend called me and I went to his place then he told what's goin' on with his PC. Fan spins and the lights... uhmmm.., lights up but no display. Back light on keyboard(and num lock) and mouse won't light up as well. When you press the power button, it'll just turns OFF in just a snap, not like a normal shutdown wherein it will wait a few seconds before turning off completely. All of that until you remove and connect back again the 6-pin on the GPU and it will magically boots up like nothing happened.

 

It is running w/ a i7 2700k, Biostar TZ68K+, GTX 1060, and 2 sticks of 4gb RAM. Forgot what's PSU on it.

 

We already did the good ol' reseating, cleaned the contacts, blow air to remove some dust, and even reapply thermal paste both the GPU and CPU.

Probably the PSU. When the GPU is powered, it is probably taking too much energy lowering the voltage

Sounds like PSU to me. Should try a different unit to be sure.

Yeah. That's what I'm thinking too because if the GPU's the one who's having issue (tho there's a debug led on the mobo itself and it is throwing a GPU error), it will boot normally and will just default to Intel's HD graphics as primary display. I'll just gonna try to use my own PSU to his PC and see if the issue still persist. Thanks guys.
